java中如何将数字1转为转为字符'1'和字符串“1”

Question

如题所述

Answer 1

int a=1;
char b = 1;
String c=a+"";

直接把1赋值给字符类型b，它会自动转换成char类型，数值1加双引号则是字符串“1”。

Answer 2

int n = 1;
char c = (char)(n+48);//用ASCII码来得到
String s = n+"";//直接加空字符串得到

Answer 3

String ab=Integer.toString(a);//字符串
char[]aa=ab.toCharArray();//字符

Answer 4

int num = 1;
String str = String.valueOf(num);
char one = Character.forDigit(num, 10);本回答被提问者采纳
